Alopecia areata

Alopecia areata is an autoimmune condition resulting in hair loss. The immune system of the body mistakenly stops hair growth for unknown reasons. Hair loss may be patchy or sparse and may involve the rest of the body in addition to the scalp. Hair in most people spontaneously regrows, though recurrences of the condition are also typical. Genetic and environmental factors play a role in hair loss, the condition may be seasonal as well.

Hair Loss

Hair loss is a common problem that affects millions of men, women, and children. At least half of adultsboth men and womenwill experience some thinning or loss of hair by the time they are 60, and many men will become completely bald. This type of hair loss is different than the loss you experience every day when you shampoo or style your hair. The average person loses about 100 hairs a day. Abnormal hair loss means that you are shedding more than that and, in the case of the most common type of hair loss, the hair will not grow back. If you think your hair loss is excessive, or if you are losing patches of hair, you should see your doctor. He or she will be able to identify the cause and discuss your treatment options.
